Corrective action for production problems: containment, root cause and verification
Turn a production problem into a closed corrective action: tell correction, containment and corrective action apart; describe the problem with facts and an is/is-not; follow an 8D structure; find both why it happened (occurrence) and why it wasn't caught (escape); and prove the fix worked before closing the record. Builds on 5 whys and fishbone basics and on controlling nonconforming material.

Skills you'll practise
- Distinguish correction, containment and corrective action, and give an example of each
- Describe a problem in measurable terms and use an is/is-not comparison to narrow the causes
- Name the 8D disciplines in order and say what each produces
- Identify both the occurrence root cause and the escape point, and propose actions for each
- Verify that a corrective action worked using before-and-after data, and decide when a record can be closed
